Perl                          vs   Lisp

one working implementation         ~4 different half finished ones
weird syntax                       weird undocumented metaprogramming
nice module repository             no repository, just use google :)
embeddable                         depends which one you use
extensible (call C)                I have no idea
one monolithic community           ~4 tiny communities
works fine in vi                   emacs MUCH more painful to extend IME

Language snobbery aside, lisp really doesn't have much going for it.

Its all just momentum.  Nobody is putting it in anything new today.
